Does anyone no how to get this companion? I saw someone with one and are DYING to get oneBristly Kevin

Witchdoctors get the helephant companion from a side quest in mooshu (I don't remember the exact location, but it connects to the valley of titans). After you defeat the necromancer who's been plaguing the land for a while, he says he'll stop and he also gives his oni servant to you for your journey. Note that only witchdoctor's get this companion normally, the rest unlock him for purchase in the crowns shop after completing the quest.
